Excavators operating in mining, quarrying and heavy construction rely on dependable hydraulic components to keep working under continuous load and harsh ground conditions. Long-term service places heavy stress on internal gears, bearings and sealing surfaces, which can lead to weak output, abnormal noise, overheating or reduced machine efficiency. The K1003131 Doosan Excavator Travel Motor Assembly is developed for Doosan DX340-5, DX340, DX350 excavators, matching the original hydraulic system to deliver reliable transmission and steady working performance.
